NEMA OUTLETS AND ASSOCIATED

NETWORKS ”, filed on March 14, 2007, the content of which is incorporated here as if fully disclosed.

Field of the invention The present invention relates generally to the distribution and management of electrical energy, and in particular to an electrical outlet, or other device associated with a local circuit (for example, single or multiple commercial or residential dependence), to monitor at least part of the circuit and control the distribution of the circuit.

Fundamentals of the electrical distribution power distribution invention are monitored and controlled for a variety of purposes. In this regard, energy distribution generally refers to transmission between a power plant and substations while electrical distribution refers to the distribution of a substation to consumers. Electricity is additionally distributed on the consumer's premises typically through a number of local circuits.

The distribution of energy can be monitored and controlled in relation to the treatment of actual or potential conditions of excess capacity. Such conditions have become increasingly common in the United States and other parts of the world due to increasing industrial and residential energy coupled

2/44 to the aging of energy infrastructure and practical limitations on new generation of energy. Overcapacity conditions are often dealt with by reducing or interrupting energy supplied to standard residential and commercial consumers, for example, total blackouts or partial blackouts. For example, during periods of peak use, periodic total blackout can be implemented where energy for grid subdivisions is sequentially interrupted to reduce the overall load on the grid.

[0005] The effects of these power interruptions can be improved to some extent. Certain high or critical value customers may be exempt from periodic total blackouts if the grid structure allows. Other critical installations or appliances can be supported by redundant, fail-safe generators or power sources.

However, for many standard customers, power outages, and the consequences of these for data systems and other vulnerable products, are simply tolerated. For these customers, interruptions are indiscriminate and, in many cases, total.

[0006] The electrical distribution is also monitored and controlled including the level of internal dependency. For example, fuses, circuit breakers, leakage indicators for earth, surge protectors and the like are generically used to interrupt or cut down electricity in a circuit if the current drawn by the circuit exceeds a certain level. These elements are typically required by code and can be customized to some extent, for example, with respect to circuits to provide high energy devices (ie dryers, air conditioners) or low

Petition 870180039271, of 05/11/2018, p. 10/59

3/44 (for example, lighting). However, these elements are generally unintelligent and limited to avoiding danger.

Typically, they do not recognize devices or types of devices when connected to a circuit, do not allow to handle larger grid needs and are not responsive enough to address certain safety issues such as potential electrocution.

Summary of the invention

The present invention relates to intelligent circuit devices such as electrical outlets, for example, standard NEMA sockets, and to customer dependency electrical systems, appliances, power distribution systems and associated processes that can use such intelligent circuit devices. The smart circuit devices of the present invention can monitor a load connected to a circuit and control the distribution of energy across the circuit. Circuit devices can also be controlled via a communication interface in order to implement a grid or location program in relation to electrical distribution or use. In this way, energy can be distributed more efficiently, building wiring and outlet safety can be increased and electrical grid capacity problems can be dealt with more effectively. In addition, the invention provides features of convenience and safety.

In accordance with an aspect of the present invention, a utility (including a system and associated functionality) provided to enable communication of

Protocol of

Internet / Transmission Control Protocol (TCP / IP) to a socket socket, for example, a standard NEMA socket socket. In this way, the socket effectively becomes a data network node or

Petition 870180039271, of 05/11/2018, p. 11/59

4/44 customer.

This allows for a wide variety of functionality. For example, plug sockets can operate as intelligent control points for electrical distribution, provide feedback on the types of devices that are currently fitted to the sockets, and selectively control the distribution of electricity through the sockets (including reducing power consumption by eliminating individual energy waveform cycles through the sockets via on / off

In addition, the sockets can be controlled over a remote network using TCP / IP communication in order to enable remote or intelligent operation of devices that are not otherwise adapted for data network control.

TCP / IP outbound technology also provides a convenient mechanism for smart devices to communicate over power lines with a remote network and facilitates standardization of such devices.

In this respect, TCP / IP has several advantages including the following:

TCP / IP is the preferred protocol for communicating with sockets for both technical and economic reasons.

TCP / IP is the largest network on the planet.

standard internet protocol, the

It is an open protocol and very unlikely to be replaced.

3. TCP implementations and support infrastructure continue to improve. In particular, it is now possible to obtain very small and light implementations of TCP suitable for processing energy that can be easily incorporated into a small space limited by heat like a socket box.

4. The overwhelming adoption of TCP / IP is triggering

[00010] According to another aspect of the present invention, a utility is provided for controlling power distribution through a local circuit device (for example, on premises) as a socket or group of sockets based on a load analysis. Specifically, the utility involves monitoring at least one local circuit device to determine information regarding a local circuit device load based on an analysis (for example, digital processing) of an electrical signal transmitted through the circuit device, and controlling power distribution through the circuit device based on the analysis. The analysis can be implemented by a digital processor on the circuit device such as on an outlet or elsewhere (for example, on a circuit breaker panel or elsewhere on a controlled circuit). For example, different electrical devices or appliances can produce different electrical signatures that can be detected in a socket. Therefore, the electrical signal can be analyzed to determine a classification of an electrical device, for example, to identify the specific electrical device or the type of electrical device (or an intelligent device can identify itself), identify distribution quality issues power supply (on supplied power or electrical wiring), provide virtual GFCI functionality on sockets specified as necessary by comparing summary current measurements with neutral current, or identifying a safety issue or load anomaly. This information can be used, for example, to reduce energy

6/44 distributed to the device (for example, by quick switching to eliminate selected cycles of the power signal or by interrupting power to the device for a given period (s)) or assigning the socket / device a level priority in the event of power loss (for example, partial blackout). Alternatively, digital analysis may indicate a short circuit, a potential shock or electrocution event, or other safety concern. In such cases, power to the socket may be interrupted. In addition, if a device switch is assumed not to be on, for example, if the resident is on vacation and a light is suddenly on, a security alert can be generated as well as an email alert.

[00011] In a related way, a fast power switching function can be implemented to control the energy distribution. Such a fast switching structure can be used in at least two ways: 1) arc suppression when switching main relays on / off; and 2) fast switching when “stealing cycles. The function mentioned last cannot be performed by switching relays due to the required operating speed. Instead, this is accomplished by solid-state switching such as triacs or MOS devices. It has been recognized that heat generation can be problematic, particularly in relation to implementations where the switching function is performed in a socket box or in other limited, unventilated contexts. To minimize heat production, a fast switching device (eg semiconductor power switch) is used in combination with a traditional mechanical relay, each controlled by a combination of analog and digital circuitry. Thus, the switching times

Petition 870180039271, of 05/11/2018, p. 14/59

7/44 speeds needed to withstand the requirements of this patent can be achieved, while the mechanical relay provides the necessary low speed switching and low heat production. Semiconductor switching devices (eg, triacs, metal oxide semiconductor, etc.) are fast, but will produce some heat. Mechanical relays are relatively slow, but produce little heat. When operated in mutual combination under microprocessor control or another digital medium, the two switching devices can provide the necessary fast switching with acceptable levels of heat production.

[00012] In accordance with another aspect of the present invention, a local circuit device such as a socket module communicates with a controller via electrical wiring of the premises. An associated subsystem includes an electrical device that receives power through a customer's electrical wiring via an electrical circuit and a switching module, associated with the local circuit device, to control power distribution to the electrical device. The utility additionally includes a socket controller to control operation of the switching module. The switching module and the socket controller preferably communicate via electrical wiring using an Internet communication protocol (for example, UDP and / or TCP / IP) or use other protocols than a local controller (for example, a device connected by internet) can gateway and / or proxy for TCP / IP in such a way that the switching module and / or a device plugged into the socket of a switching module can communicate via TCP / IP. The subsystem can be used to coordinate energy distribution through the socket in relation to a larger energy distribution system, for example, the

Petition 870180039271, of 05/11/2018, p. 15/59

8/44 power grid. Alternatively, the subsystem can be used to remotely monitor and control the operation of the electrical device, for example, over the internet.

[00013] The present invention can also be implemented in the context of a data center. Data centers often include a power strip including plugs associated with two separate sources. For example, such a power strip product is being developed by Zonit Structural Solutions. The power strip can thus implement switching functionality as discussed above in order to provide redundant power sources, for example, for critical data devices. However, it will be recognized that it will not be generally desirable to steal cycles from data devices and that switching will normally only be implemented with respect to power interruptions. Consequently, thermal balance concerns are greatly reduced, and the fast power switching functionality may not be necessary, but it can be implemented nonetheless, if practical.

[00014] In a residential or commercial context, a controller can communicate with the sockets via TCP / IP protocol, as discussed above. When using power lines for such communications, it is useful to provide some mechanism to avoid crosstalk. That is, as the power lines that finally extend between multiple sockets effectively define a single electrical bus or are supported by interconnected waveguides, instructions from the controller intended for a first socket could be received by and acted upon by a second socket without some mechanism to limit message transmission or allow sockets to discriminate between messages

Petition 870180039271, of 05/11/2018, p. 16/59

9/44 received.

An addressing mechanism for addressing messages to individual sockets in a set of controlled sockets can address the issue in a given control domain. It is also desirable to limit the transmission of messages across power lines in order to keep the energy waveform clean.

This can be accomplished by canceling or attenuating the signal at a local controller control point - for a set of power sockets. Specifically, the location controller is associated with a transceiver to insert communication signals directed to the controlled sockets on a power line and to receive communication signals from the sockets through the power line. An attenuation or cancellation device can be provided external to that transceiver, that is, between the transceiver and the power network external to the controlled domain. In this regard, cancellation involves specifically eliminating specific signals such as using an active cancellation signal based on the signal to be canceled. Attenuation refers to the use of a frequency-dependent filter to selectively exclude the frequency or frequencies used to communicate via the internal power wiring from the transmission to the external power network.

[00015]

In addition, it will be recognized that the control functionality discussed above can be implemented in an electrical device instead of an outlet or other local circuit device (or in an intermediate unit disposed between the electrical device and the outlet). That is, from a communication point of view, there is little distinction between the device and the outlet where the device is fitted; communications can be transmitted over power lines all the way to the device.

In this way, the circuit breaker

Petition 870180039271, of 05/11/2018, p. 17/59

10/44 intelligent or other control and communication technology can alternatively be implemented by retro-fitted or custom-made devices. In the context of a data center, data can be accumulated and viewed (via an LED or LCD panel or network interface) over a power strip, an associated controller or remotely. In this regard, the need for additional wiring to support instruments (such as thermometers, airflow sensors, door lock sensors, humidity or light sensors, etc.) is reduced, thereby simplifying maintenance, conserving frame space and increasing the flow of cooling air.

[00016] In accordance with a further aspect of the present invention, an intelligent electrical outlet is provided. The socket includes a socket for receiving a standard electrical plug in order to establish an electrical connection - between a device associated with the plug and a dependency wiring system associated with the socket - and a digital processor to control power distribution through the socket. For example, the digital processor can be incorporated into a circuit board that can be housed in a standard socket housing, for example, to perform fast power switching functionality as described above. In this way, intelligent control and monitoring can be implemented at the individual outlet level or individual socket level of a power distribution system.

[00017] In accordance with an additional aspect of the present invention, an energy distribution system is provided that allows greater monitoring or control of energy distribution, including control at the level of customer facilities. The system includes an energy grid to distribute energy through an

Petition 870180039271, of 05/11/2018, p. 18/59

11/44 geographic distribution area, one or more grid controllers to control energy distribution through the power grid and a number of customer (local) controllers. Each of the customer dependency controllers controls the distribution of power in a specific customer dependency based on communication between the customer dependency controller and at least one of the grid controllers. For example, customer dependency controllers can be implemented at the customer dependency level and / or at the individual outlet level at the customer premises.

[00018] It is noted in this regard that the local controller (if implemented at the outlet and / or elsewhere on the customer's premises) can run purely local programs, programs driven by external controllers (for example, grid), or combinations of themselves. For example, the local controller can control power distribution based on local programs referring to bypass wiring current limits, safety programs, protection programs, or other programs that do not require communication with or coordination with a grid controller or another external controller. Conversely, the local controller can be used to run a grid-based program or another external program, such as a partial dimming operating mode. In still other cases, the local controller can make decisions based on both local and external conditions. For example, a grid controller can instruct local controllers, on a mandatory or voluntary basis, to operate in conservation mode. Local controllers can then perform a conservation operation mode according to local programs, for example, regarding which devices can be turned off or

Petition 870180039271, of 05/11/2018, p. 19/59

12/44 operated in low power mode or which devices have priority for continuous operation.

[00019] In accordance with a further aspect of the present invention, a method is provided for addressing overcapacity conditions in an energy distribution grid. The method includes the steps of identifying an overcapacity condition with respect to at least part of an energy distribution grid and treating the overcapacity condition by controlling the energy distribution at a finer level than the subdivision finer distribution of the energy distribution grid. In particular, the overcapacity condition refers to a condition that potentially requires a reduction in the power supplied to standard residential and commercial customers, for example, conditions that have conventionally resulted in total blackouts or partial blackouts. In some cases, such conditions have been dealt with by periodic total blackout, as discussed above, where a grid is divided into a number of grid subdivisions, and energy for those grid subdivisions is sequentially interrupted to reduce the overall load on the grid. The present invention allows to treat such conditions at a finer or more flexible level than these network subdivisions. In this way, individual homes, business customers, or any desired set of customer facilities can be managed as a grid topology independent group. For example, power distribution can be controlled in the electrical distribution instead of the energy distribution part of the distribution network. As mentioned above, energy distribution generally refers to the transmission between a power plant and substations while electrical distribution refers to the distribution

Petition 870180039271, of 05/11/2018, p. 20/59

13/44 of a consumer substation. For example, according to the present invention, the distribution of energy can be controlled at the level of customer facilities or even at the outlet level at a customer facility. In addition, energy distribution can be controlled by reducing energy distribution, for example, by eliminating certain cycles, or by interrupting energy distribution. In this way, blackouts or partial blackouts can be avoided or implemented more intelligently in order to avoid the damage or inconvenience associated with such blackouts or partial blackouts.

additional control

In accordance with the present invention, a device that still has a system is fitted to an aspect provided for in an intelligent outlet.

The system can be used in a variety of contexts, including data center control, as well as control of electrical devices in a residential or commercial environment. The system includes a local controller and one or more smart sockets.

local controller can communicate with a remote controller via a first protocol and with the smart socket via a second protocol the same or different from the first protocol.

in that respect, local controller can act as a protocol gateway to translate messages between the first second protocols. For example, a local controller can communicate with the remote controller over a remote network such as the internet. In addition, the local controller can communicate with the smart outlet via power lines, wirelessly or through another communication path. In that regard, the communication between the local smart socket controller is preferably conducted according to

Petition 870180039271, of 05/11/2018, p. 21/59

14/44 with a TCP / IP protocol adapted to the local environment. In an implementation, the local controller is implemented in combination with a power distribution unit in a data center. The smart plug can be implemented in combination with a data center power strip. In this way, the data center device can be conveniently controlled from a remote location. Besides that,

wanted.

[00021] According to a further aspect of the present invention, a local controller can function as a communication gateway for multiple devices, smart sockets or combinations of devices and smart sockets associated with the local controller. In this regard, the local controller can perform TCP / IP via power wiring functionality or another data protocol. The local controller can then gateway all local devices to a WAN. In this way, all local devices can communicate with and be controlled over the WAN. Some examples of what this enables include: allowing a smart refrigerator to order food from a market as needed; allow a furnace to report through the WAN that carbon monoxide is leaking into the forced air; and an air conditioner can report over a WAN that the fan motor is about to fail.

[00022] The local controller can gateway such communications in at least the following ways. First, and preferably from a standardization point of view, such communications can be end-to-end TCP / IP. The local controller acts

Petition 870180039271, of 05/11/2018, p. 22/59

15/44 as a TCP / IP router (and power line inserter). The local controller can also act as a firewall. In this case, the final two ends of the communication “speak TCP / IP. Second, the local controller can gateway and proxy between TCP / IP and another communication protocol (via power wiring). Again, the local controller acts as a gateway router and can act as a firewall. In this case, the device being controlled speaks in its native communication protocol (which could be used to encapsulate TCP / IP) to the local controller and the local controller speaks TCP / IP (which, conversely, can be used to encapsulate the communication protocol). device communication) for the WAN.

[00023] The TCP / IP gateway provided by the local controller, as discussed above, has several functions. First, the gateway provides universal and uniform WAN TCP / IP connectivity. All smart sockets and electrical devices connected to them with appropriate adapters or internal hardware can communicate over TCP / IP with a WAN (Internet) via the local controller. This can be done regardless of which protocol is used to communicate through the facility's power wiring, however it is preferred to be over TCP / IP as well. The TCP / IP communication functions offered by the controller are those that are commonly used to interconnect any two TCP / IP networks. Some of which include the following:

1. Routing. TCP / IP data transmissions from smart sockets and devices on the power wiring network to the TCP / IP WAN are enabled and vice versa.

2. Network address translation. Only a routable public TCP / IP address on the TCP / IP WAN is required for complete connectivity.

3.

Protocol encapsulation.

If one or more non-TCP protocols are used by smart sockets and / or devices on the power wiring network, they can be bidirectionally encapsulated and thereby enable end-to-end communication between the device on the power wiring network and an end point on the WAN TCP / IP. TCP / IP can be used to encapsulate the protocol (s) used in the power wiring network and conversely the power wiring network protocol can be used to encapsulate TCP / IP to a socket or device in the power wiring network.

last mentioned is possible, but it is not a preferred method.

4. Proxy server role.

If desired, all devices on the power wiring network can be proxied by the Proxy functionality

Controller TCP / IP. This can be a convenient way to communicate with and control the sockets and devices on the power wiring network.

gateway also provides privacy and security functionality.

The TCP / IP gateway on the local controller also acts as a firewall to monitor and control the data connections from the smart wired network sockets and electrical devices connected to devices on the TCP / IP WAN. Programs can be defined to control, limit and report on this connectivity.

In this way, the privacy and security of the home owner or facility owner can be protected.

Detailed description [00026] The present invention is directed to

Petition 870180039271, of 05/11/2018, p. 25/59

18/44 smart local circuit devices that can control power distributed to an electrical device through a circuit and / or report information about or an electrical device connected to a circuit. This allows you to remotely monitor and / or control electrical devices, including standard electrical devices that are not specially adapted for such monitoring or remote control, which can be useful in a wide variety of applications. In the description that follows, the invention is exposed in the context of standard NEMA electrical socket outlets equipped with logic to monitor connected loads from sampling energy waveforms (for example, electrical appliance devices) selectively control the outlets.

Later, certain systems to take advantage of this functionality are described. In particular, power grid distribution systems and data center appliance control and power distribution systems are described.

It will be recognized that circuit devices other than electrical socket outlets, and applications other than mentioned data center and power grid applications, are supported by the technology of the present invention.

Therefore, the following description should be understood as illustrative and not as a limitation.

The invention can be understood more fully by referring to figures 1-4. Referring primarily to figures 1A and 1B, front and side views, respectively, of an intelligent socket according to the present invention are shown. The illustrated socket 100 includes two standard sockets 102 accessible through a face 104. Each of the sockets 102 includes a socket body 106 to receive a standard electrical plug and establish an electrical connection between plug pins and

Petition 870180039271, of 05/11/2018, p. 26/59

19/44 wiring 110 associated with the customer's premises wiring system, for example, a residence or firm. The illustrated socket 100 additionally includes a controller 108 mounted in the socket housing 112 in the illustrated embodiment. For example, controller 108 can be incorporated as an integrated circuit panel. As will be discussed in more detail below, controller 108 is operative to monitor a load against each of sockets 102 and control power distribution to sockets 106. For example, this can be done to classify an electrical device connected through the sockets 106 or identify a security risk. Power distribution to sockets 102 can be controlled to alleviate a security concern, increase energy distribution efficiency, remotely control an electrical device connected to one of sockets 102, or address an effective or potential overcapacity condition of an energy grid. Controller 108 may also be operative to communicate with other controllers, for example, at the customer's premises, at separate customer premises or with network controllers outside the customer premises. For example, such communications can be conducted over power lines, wirelessly or through other communication paths.

[00028] Figure 2 is a schematic diagram of an energy distribution system 200 according to the present invention. The illustrated system 200 includes an electrical device 202 that is plugged into an electrical socket 204. Socket 204 selectively receives power from a power source 208, such as an electrical grid, through a circuit breaker 206. Circuit breaker 206 can be located in the socket 204 or in a remote location, such as a control panel

Petition 870180039271, of 05/11/2018, p. 27/59

20/44 circuit breakers or other location associated with a circuit to supply electricity to socket 204.

In the illustrated mode the switch

206 is operated by a processor 212 based on monitoring an electrical signal in socket 204. For example, processor 212 can be located in the socket, in a separate location on the customer's premises (for example, a computer configured to control multiple outlets) or elsewhere. In that regard, the signal on the socket

204 can be monitored to identify an electrical signature identifying device 202 or type of device 202. It will be recognized that different types of electrical devices have different characteristics in relation to how they charge the electrical system. For example, an electric pump may have a different signature than an electric light.

This signature can be related to the energy drawn, a time-dependent characteristic of the energy drawn, or another characteristic of perceptible signal from the energy signal distributed through the socket

204. Alternatively, an intelligent device can identify itself to the sockets, for example, by transmitting a standard identification code.

nature of the signature can be determined theoretically or empirically. For example, heuristic logic can be used to learn to form electrical signatures in parameters for different devices of interest. Such subscription information can then be stored in a subscription database

214. Therefore, the illustrated system 200 includes an analog-to-digital converter 210 for digitally sampling the electrical signal at socket 204 and providing digital information representative of the signal to processor 212.

This digital information is then

Petition 870180039271, of 05/11/2018, p. 28/59

21/44 processed by a 216 signature recognition module of processor 212 to identify the signature. For example, the digital input signal can be algorithmically processed to determine various parameters of the signal, which can then be compared with parameters stored in the subscription database 214 to match the input signal to one of the stored signatures. It will be recognized that the signature information can also be used to determine a state of the device 202 or to detect an output of the device (for example, in the event of the device 202 being a sensor providing an output signal).

[00031] An output from the signature recognition module 216 can then be used by a decision module 218 to control power distribution to socket 204. In that regard, decision module 218 can also use information input from a controller 220 , which can be arranged at the outlet, elsewhere on the customer's premises (such as a computer), or elsewhere. In an implementation, the controller is in communication with the larger power distribution system, for example, the power grid. For example, if device 202 is recognized as a device that can operate at a reduced power level, decision module 218 can operate circuit breaker 206 to reduce power distribution to socket 204. In this regard, it is possible to “steal certain number or percentage of energy signal cycles without unacceptably affecting the performance of certain devices. In such applications that involve frequent switching, the quick switching functionality discussed above allows operation in the available thermal balance, as will be discussed below. Appropriate switching mechanisms are

Petition 870180039271, of 05/11/2018, p. 29/59

22/44 described in US provisional patent application serial number 60 / 894,842 and US patent application serial number [not yet assigned], which claims priority thereof, and US provisional patent application serial number 60 / 894,848, and US patent application serial number [not yet assigned], which claims priority thereof, which are hereby incorporated by reference. Decision module 208 can be programmed to implement such energy reduction by the customer or an energy supplier, such as a utility company.

[00032] In other cases, controller 220 may direct decision module 218 to enter an energy saving mode. For example, this can occur when an overcapacity condition is identified with respect to the power grid or a part of the power grid. In such cases, decision module 218 can reduce or eliminate power distribution for certain classes of devices.

[00033] As an additional example, signature recognition module 216 may determine that device 202 will not match any signature authorized for use in socket 204. In such cases, decision module 218 may operate circuit breaker 206 to interrupt distribution of power from source 208 to socket 204. Similarly, decision module 218 can interrupt power distribution in the event of a potential short circuit, potential electrocution or shock, or other potential safety hazard event .

[00034] It will be recognized that system 200 can be used for a variety of other purposes. For example, processor 212 can operate circuit breaker 206 to turn on lights or operate another electrical device in a

Petition 870180039271, of 05/11/2018, p. 30/59

23/44 random or periodic basis to create the illusion that the premises are occupied and thus discourage crime.

In addition, the processor can monitor socket 204, for example, identify activities when premises are assumed to be vacant, thereby identifying unauthorized use or possible crime. In addition, the processor

212 can be used to allow remote control of socket 204, for example, to allow an owner to remotely operate electrical devices over the internet. It will be recognized that the various functional components mentioned in this discussion can be combined on a common platform or distributed across multiple platforms (for example, on the outlet, a separate platform from customer facilities or other platforms) in any appropriate way.

[00035] Figure 3 illustrates a system 300, according to the present invention to enable remote monitoring and / or control of multiple sockets. In particular, system 300 includes a number of smart sockets 302, which can be, for example, sockets as discussed above, with reference to figures 1A and 1B. Sockets 302 communicate with a local controller 304, which can be, for example, a computer or internet terminal located on the customer's premises. For example, smart sockets 302 and local controller 304 can communicate via an internet protocol (for example, TCP / IP) or a proprietary protocol that is formed at a gateway with the WAN via electrical wires from the customer's premises . Local controller 304 can, in turn, communicate with a remote controller 308 over a remote area network 306 such as the Internet. In this regard, communication between local controller 304 and remote controller 308 may involve wireless (for example,

Petition 870180039271, of 05/11/2018, p. 31/59

24/44

IEEE 802.11, Wi-Fi, telephony or other wireless) or other data network links. The remote controller 308 can be operated by a private or public party. For example, the remote controller may comprise a computer used by a customer's premises owner to remotely control sockets 302, a computer monitored by a security contractor to monitor activities on sockets 302, a power grid controller operated to implement blackouts smart totals or partial blackouts or any other entity.

[00036] Figure 4A illustrates a 400 power distribution network to intelligently control the power distribution. The illustrated network 400 includes several client facilities 402 connected to a 403 power grid. The 403 power grid receives power from several 408 power plants, and power distribution through the 403 grid is controlled by a central grid control system. 406 and optionally, a number of regional controllers 404, as substations. As discussed above, each of the 402 customer facilities can include a number of smart outlets. These outlets can be controlled in response to instructions from the central control system 406 or regional controllers 404. Thus, for example, customers may choose or be required to install smart outlets that operate in response to such instructions from the system 406 central control or 404 regional controllers to reduce energy consumption

on a routine basis or at the event in conditions in excess capacity. [00037] Although The functionality of control is discussed in the figure 4A in relationship The a system in

Petition 870180039271, of 05/11/2018, p. 32/59

25/44 grid control and substations, it will be recognized that the sending of the control message does not need to be through power lines and that such control is not limited by network topology. This is explicitly shown in figure 4B. In this case, control messages are sent to individual customer facilities via a separate network such as the 411 internet. In this way, a given set of instructions can be provided to a subset of (shaded) homes independent of the associated power network topology to substation 404. In addition, as discussed above, instructions can be implemented on a finer scale than individual residences, for example, on a socket-by-socket basis (as indicated by partially shaded residences). In this way, for example, partial dimming can be implemented intelligently, for example, by disrupting power to non-critical devices and / or stealing power cycles from appropriate device types.

[00038] Figure 5 illustrates a process 500 for monitoring and controlling electrical devices in accordance with the present invention. This process 500 will be described with respect to applications that enable monitoring and remote control of electrical devices connected to smart outlets as described above, including applications to allow control of electrical devices by the operator of a power grid. The illustrated process 500 is initiated by establishing (502) network programs related to the use of energy in the network. For example, such programs can be established by an electrical utility to deal with potential or actual overcapacity situations that were previously dealt with, for example, by total blackouts or periodic partial blackouts. It will be recognized that these programs

Petition 870180039271, of 05/11/2018, p. 33/59

26/44 may be established in any way that is considered useful by the energy supplier. Some examples are provided below:

1. Efficiency mode [00039] In the efficiency mode, individual households that are subject to the program are instructed to reduce energy consumption by a certain percentage. This can be implemented in the home by disabling selected devices and / or reducing power consumption by certain devices, as will be described in more detail below.

2. Partial dimming mode [00040] In partial dimming mode, the highest loads (for example, air conditioning, electric heating, etc.) are identified and closed in series for short periods of time (for example, 5 - 10 minutes) to reduce overall peak load. To prevent all houses and firms from closing these charges at once, instructions can be sent to homes or executed at homes randomly, pseudo-randomly or otherwise distributed over time. For example, a residence can be assigned an identification code by a random number generator. Subsequently, instructions for executing the partial dimming mode can be sent or executed on a time-dependent basis as a code function, for example, at a given time, the partial dimming mode can be performed by all households having a identification ending in number 5. Statistically, this can be done in such a way that the peak load will be reduced by the required percentage, but the impact for end users is minimized.

3. Total darkening mode [00041] In total darkening mode, loads

Petition 870180039271, of 05/11/2018, p. 34/59

27/44 criticisms (eg refrigerators, lights, radios, radiant heating pumps, etc.) can be identified and allowed on a total or reduced energy basis as appropriate. Non-critical items can be disabled.

[00042] It will be recognized that many other modes of operation and associated programs can be defined. In the illustrated process 500, after the network programs have been established, local rules are established (504) to implement the network programs. This optional implementation allows commercial or residential customers to have some input, for at least some programs, regarding how such programs will be implemented. For example, the customer can define which devices or devices are critical for the purpose of running a partial dimming or total dimming program. In addition, a customer can be left to determine whether a given power reduction will be performed by disabling devices, reducing power drawn by devices or some combination of them. In addition, in certain implementations, consumers may be allowed to request periods of time during which energy use will be reduced to achieve the purposes of the program in question. While it may not be possible, as a practical matter, to accommodate all of these requests, some requests can be accommodated at least to a point, thereby reducing the impact on users.

[00043] Additional local programs and rules can be established (506) to take advantage of smart outlets. For example, a customer may choose to operate in an efficiency mode at certain times or under certain conditions (for example, while on vacation or when

Petition 870180039271, of 05/11/2018, p. 35/59

28/44 dependencies are otherwise vague). In addition, as mentioned above, a customer may wish to monitor the types of devices that are plugged into individual sockets or power usage, for example, for security purposes. In this regard, the customer may wish to be notified of certain events, for example, when a light is on when no one is supposed to be present on the premises, to have a third party notified of certain events (for example, an emergency service provider or security) or prohibit certain uses (for example, prohibit the use of lights, appliances, operation of electronic door locks or the like at certain times or under certain conditions).

[00044] As an example, programs that can be implemented by a customer include the following:

1. Safe travel mode [00045] In safe travel mode, devices such as lights, radios and the like can be turned on and off in a random, pseudo-random or selected pattern to make it look like the house or business is occupied. This can be pre-programmed or controlled, for example, by the owner of the house / firm from a distant location. Regarding this last point, the devices can be controlled remotely through appropriate messages transmitted over the internet or another network. In addition, in secure travel mode, an email alert can be sent to a selected address in the event that a device is manually switched on. Alternatively or additionally, an emergency or security service provider can be contacted.

2. Way of living [00046] Using a local interface or a remote network interface, an occupant can program when

Petition 870180039271, of 05/11/2018, p. 36/59

29/44 turn on / off any device. For example, selected devices can be turned on or off at a predetermined time according to a wake-up time, departure to work time, return to work time or bedtime.

3. Efficiency mode [00047] In efficiency mode, the system can automatically turn off lights or other devices for pre-set periods of time. For example, specified sockets can be turned off during periods of time when the residence is normally unoccupied or residents are sleeping. As an enhancement to this mode, devices can be monitored to determine when they were manually powered off. When this occurs, the system can assume that the occupant wants to manually turn the device back on and therefore connect the socket.

4. Safe mode [00048] In safe mode, the user can select to disable certain sockets that can be reached by young children or unused sockets that are in a child's bedroom.

[00049] In addition to the various programs and rules that were discussed above, several advantages are provided by the system of the present invention. In particular, since the system can detect short circuits in very short times (for example, in 1/60 of a second or less), the potential for serious electric shocks is greatly reduced, not to mention the damage caused to the device by short circuits. In addition, the ability to analyze the energy signature on the sockets and then compare it to a standard or limit has several advantages, including the following:

Petition 870180039271, of 05/11/2018, p. 37/59

30/44

1. Quick reaction to shorts [00050] All supported sockets become fast-acting in response to a short circuit and can be deactivated very quickly, thereby increasing safety for people and devices.

2. Reduction of old wiring or circuit breakers [00051] Circuits can be reduced if your wiring is old or otherwise deteriorating. In this regard, the socket or set of sockets in a circuit can be programmed to only allow a certain total current load, which can be set below the circuit breaker level and code. In this case, the central unit monitors the total current load in a branch and can proactively control the load by disconnecting loads or reducing power for certain sockets. The central unit determines which outlets are connected to which legs of the circuit through energy signature analysis. The order of which sockets are disconnected or reduced power can be defined through a program with respect to the type of load. This program can be manually adjusted or canceled if desired, or it can be mandatory. This type of active power management can help to make premises less prone to fire. In this regard, it is observed that many fires in homes are caused by electrical wiring problems. Therefore, this type of system can be determined by a code and / or compensated by insurance providers.

3. Wiring leg monitoring [00052] This is done by monitoring the current close to the input source through a socket next to the power input in the house and monitoring the most distant current in a branch tap. The difference in

Petition 870180039271, of 05/11/2018, p. 38/59

31/44 power signatures, as recognized by the respective outlets, will indicate whether the wiring between the outlets is not working properly. If this occurs, several actions can be taken. For example, a socket can be instructed to turn off the panel circuit breaker for the circuit by inducing a short circuit for a period of time, tripping the circuit breaker, or turning off all sockets on that branch circuit. If this is not effective for opening the circuit breaker, an alert can be sent via the communication paths described above. Such an alert can be sent for any life safety condition or other specified condition.

[00053] In the illustrated process 500, after the desired programs and rules have been established, loads are monitored (508) to identify load signatures. As discussed above, different devices can have different signatures that can be identified by analyzing the power signal or can communicate an identification code to the controller. In this way, the device (s) fitted to a given outlet, or the general or specific class of such devices, can be determined. A controller such as a local controller discussed above can develop (510) and update a load map for support sockets on the premises. In this way, at any given moment, the local controller can store an estimate with respect to which devices or classes of devices are fitted through which sockets of the premises. It should be noted in this regard that only a subset of all sockets in a given dependency can be smart sockets or only a subset of sockets (even if all sockets are smart sockets) can be participating sockets with respect to one

Petition 870180039271, of 05/11/2018, p. 39/59

32/44 system implementation or in relation to individual programs.

[00054] During system operation, a controller such as a local controller can identify (512) a condition governed by the program. For example, in the case of an external program such as a change in the mode of operation determined by the grid power supplier, the condition can be identified based on the receipt of an instruction from the external source. For example, the local controller can receive a message from the utility provider specifying transition to an efficiency mode or a partial dimming mode. Alternatively, the condition can be identified based on the occurrence of a programmed program condition. For example, if the efficiency mode operation requires certain sockets to be switched off at certain periods of time, the beginning of such a period of time can be identified as a condition governed by the program. As an additional alternative, the existence of a condition governed by a program can be identified based on the analysis of load information communicated from an intelligent socket to the local controller. For example, excess load from a circuit, manual operation of a device in contravention of a program, or other load-based conditions can be identified.

[00055] After identifying this condition, a controller such as the local controller can access (514) rules to implement the relevant program. Accordingly, if the electrical utility provider specifies a conservation mode of operation, local rules can be consulted to implement the required energy reduction usage according to customer preferences. Similarly, during safe operation, if a

Petition 870180039271, of 05/11/2018, p. 40/59

33/44 electrical device is manually operated, the owner or an emergency or security service provider can be contacted according to rules defined by the owner. In any event, the rules are applied (516) in relation to all supported sockets or a specified subset thereof in order to give effect to the desired program. Specifically, instructions can be transmitted (518) to the sockets affected by the local controller. These instructions can, for example, cause a socket to be turned on, turned off, or operate in a power-reduced use mode. The smart socket then operates to execute (520) the instructions.

[00056] In this regard, as noted above, the smart socket may include a fast-operating circuit breaker operable in combination with a traditional mechanical relay as discussed above. This circuit breaker and associated relay can be operated to connect the socket, turn it off or steal cycles of the power signal. Regarding this last point, the circuit breaker can be controlled by analogue or digital devices to perform this switching at point of zero or near zero potential of the energy signal in order to reduce the potential for sparking. In addition, such a circuit breaker is preferably designed to function in the thermal balance of the application environment. In this regard, it is observed that socket boxes can, in some cases, be surrounded by insulation in such a way that heat dissipation is largely limited to heat transfer across the face. The present invention can be implemented in the associated thermal balance. However, if necessary, face structures can be modified to provide greater thermal balance for system operation. For example, the associated electrical boxes can extend for

Petition 870180039271, of 05/11/2018, p. 41/59

34/44 some distance from the wall in order to provide larger heat transfer surfaces or active heat dissipation, for example, by miniature fans, can be employed.

[00057] Another application where it may be desired to control electrical devices according to a program or to allow remote control of such devices is the data center environment. In this regard, it is often useful to be able to control power for electronic data processing devices. This capability is especially useful for situations where the device is densely packed as in a data center away from the user who wants to control the device.

[00058] Figure 6 illustrates a 600 system to enable such control in a data center environment. In particular, the illustrated system 600 includes a number of data center devices 601-609. Such 601-609 devices include a number of 601-606 data devices such as servers, storage devices and the like. In addition, devices 601-609 include a number of 607-609 sensors such as temperature sensors, humidity sensors, cabinet or cage door lock sensors and the like. The 601-609 devices are typically mounted on one or more two or four-post device frame data center frames.

[00059] In the illustrated embodiment, devices 601-609 are plugged into sockets 612, 634 and 644 associated with a number of power bands 610, 630 and 640. As will be discussed in more detail below, these sockets 612, 634 and 644 they can be smart sockets as generically described above.

[00060] Power ranges 610, 630 and 640 are connected by power lines to a local controller

Petition 870180039271, of 05/11/2018, p. 42/59

35/44

650. In this case, the 650 local controller can be embedded in a data center power distribution unit as marketed by Zonit Structured Solutions. Generally, the power distribution unit includes several output ports 654 for transmitting power from power sources 660 to power ranges 610, 630 and 640. The power distribution unit can be associated with multiple power sources 660 as a source A and a source B to provide fail-safe, redundant power for critical devices. In this regard, ports other than output ports 654 can be associated with sources other than energy sources. In addition, certain devices may have connections to multiple power bands, as generically indicated in the spectrum by 620 redundant power bands, to provide fail-safe operation. In that regard, such critical devices may be equipped with multiple power cords or an appropriate cord assembly with a quick-change unit may be provided as described in US provisional patent application serial number 60 / 894,842, and US patent application. serial number [not yet assigned], which claims priority from it, which are incorporated here for reference.

[00061] The illustrated system 600 includes a number of remote elements and / or program-based operation of the 601-609 devices. Specifically, the local controller 650 includes a processor 655 as a single panel computer to perform local controller functionality as described above. In particular, the 655 processor enables wired or wireless communication between the local controller 650 and a remote controller 670 through a 680 network interface. The 655 processor also enables communication between the local controller 650 and

Petition 870180039271, of 05/11/2018, p. 43/59

36/44 smart sockets 612, 634 and 644. Such communications between local controller 650 and remote controller 670 can be conducted over the Internet using a standard Internet protocol that involves TCP / IP protocol and uses UDP and TCP / IP packets. Communications between the local controller 650 and sockets 612, 634 and 644 are also preferably conducted according to a TCP / IP protocol and can be adapted to the local environment. In this regard, communication between the local controller 650 and sockets 612, 634 and 644 can be conducted over power lines, wirelessly in accordance with an IEEE 802.11 protocol or in any other appropriate mode. It will be recognized that customized messaging can be provided in this regard to accomplish the purposes of the 600 system. Therefore, the 655 processor can function as a protocol gateway to translate between the protocol for communication between the remote controller 670 and the local controller 650 and the protocol used for sending an internal message between local controller 650 and sockets 612, 634 and 644. Devices can be plugged into smart sockets and use the controller as a gateway to the data center LAN (instead of or addition to the WAN).

[00062] In the illustrated implementation, communications between the local controller 650 and sockets 612, 634 and 644 are conducted through the power lines between them. This is advantageous on dedicated communication lines not required since it is problematic in a data center environment due to the complexity of additional wiring and potential interference with cooling air flows. In this regard, each of the output ports 654 of the local controller 650 can be associated with a power wire communication interface 651-653. These

Petition 870180039271, of 05/11/2018, p. 44/59

37/44 interfaces 651-653 are operative to induce message sending signals on the power lines as well as removing message sending signals that enter from the power lines in order to provide effective electrical isolation from the different communication paths. Similar power line message interfaces 611, 631633 and 641-653 are provided with respect to power ranges 610, 630 and 640 for the same reasons.

[00063] Each individual socket in a power strip can be controlled independently or all sockets in a power strip can be controlled as a group according to the present invention. Thus, in the illustrated system 600, all sockets 612 in range 610 are associated with a single communication interface 611. Similarly, all sockets 612 in range 610 can be associated with a common logic element to monitor electrical signatures or receive messages from from devices 601-603.

[00064] On the contrary, each socket 634 and 644 of the energy bands 630 and 640 is associated with its own independent communication interface 631-633 and 641-643 in the illustrated modality. For example, each socket 634 and 644 can have dedicated wiring or the signals transmitted through the power wiring can be multiplexed with respect to the individual sockets (for example, multiplexed by time division, multiplexed by frequency division, multiplexed by code division , etc.). In this way, devices 604-609 associated with sockets 634 and 644 can be individually controlled, and devices 604-609 can independently send messages to local controller 650 and internal, in turn, remote controller 670. With respect to the aforementioned finally, it will be recognized that it may be desired to provide shipping

Petition 870180039271, of 05/11/2018, p. 45/59

38/44 message to remote controller 670 based on output from sensors 607-609.

[00065] Alternatively, a single transceiver for each source of energy (for example, sources A and B can be used for induce signals in the associated wiring and a

a single signal canceller or attenuator, as discussed above, can be used to substantially prevent transmission of communications to external power lines. This is generally shown in figure 8. In particular, figure 8 shows a control system 800 for a set of sockets that defines a controlled domain. Sockets can include multiple 802 socket outlets (typical for commercial or home environments) and / or a number of 805 plug strips or adapters (typical for data center environments) that can be arranged in one or more branch circuits

806.

[00066] The sockets are controlled by a local controller 808, which can be, for example, incorporated in a personal computer (typical for domestic or commercial applications) or in a single board computer incorporated in a power distribution unit of a data center. The local controller uses a transceiver 810 to insert signals into the network 812 and branch circuits 806 to communicate with the sockets and receive signals from the sockets. A signal isolating device 814, which can be a signal canceller or signal attenuator, as described above, substantially prevents the transmission of these signals to external power lines (outside the controlled domain) 816. This structure can be replicated to A and B power sources in a data center. It will be recognized that thus having all the sockets controlled in a guide

Petition 870180039271, of 05/11/2018, p. 46/59

39/44 single wave (or two waveguides in the case of a data center with A and B power sources) is a cost-effective implementation. Communication with separate sockets can be distinguished by the use of an appropriate addressing scheme.

[00067] Figure 7 illustrates a process 700 that can be implemented with respect to the operation of the present invention in the context of a data center. Process 700 is initiated by establishing (702) rules for devices or classes of devices. For example, these rules can set preferences for turning devices on or off, establishing groups of devices to be controlled collectively, determining who can access devices and at what times, etc. The 700 process also involves developing (704) a plug / outlet pairings map. In this regard, it is possible to identify devices or classes of devices based on a signature analysis, as described above. Alternatively, a data center user can define which devices are connected to which sockets of which power bands and which power bands are connected to which power distribution unit outlet ports. For example, in this way, the user can define groups of devices that will be operated collectively (for example, by fitting the devices into a power range that is operated as a unit) and can specify critical devices for fail-safe operation. Such an operation can then be performed simply by plugging the devices into the correct outlets of the correct power ranges and fitting the power strips to the correct outlet ports of the power distribution unit. The execution of this energy structuring can be facilitated by means of appropriate indicators, such as LEDs,

Petition 870180039271, of 05/11/2018, p. 47/59

40/44 or small screen units provided in the power ranges and / or power distribution unit. In this way, devices can be easily plugged into appropriate outlets.

individual operator device

The power bands then receive either a controller to disconnect or connect a device. A remote controller is instead communicated to power or discussed above or (708) an input to the sockets from the local or remote. For example, a remote controller can choose the appropriate device or message for the local controller, which is transmitted by its socket from the local controller socket through the wiring of power to the sensor, to devices and to the power

Alternatively, a signal, such as a signature analysis or a track signal as an output signal, will be received in the socket from one of the communicated to the local controller (and, if appropriate, to the then processed remote controller). Any entry (710) using the appropriate map mentioned rules. In this way, for example, an instruction from a remote controller to shut down certain devices can be performed by consulting the map to identify the sockets associated with the appropriate devices and then communicating a shutdown signal to those sockets. Similarly, a signal from a device like a sensor can be interpreted by consulting the map to determine which sensor transmitted the signal and then cease and apply the appropriate rules to process the signal.

[00069] In addition, the ability to interrupt current from the socket described above allows the use of an additional bifilar coiled transformer to sense unbalanced current in the load and interrupt the

Petition 870180039271, of 05/11/2018, p. 48/59

41/44 distribution of energy to the load under certain conditions. This characteristic is generally similar to common leakage circuit breakers (GFCI). It differs in that it uses the general purpose disconnect relay for the effective disconnection means in the event of an unbalanced current condition. It also differs in that the detection and decision to disconnect is not performed in the same way as a traditional GFCI, in which the microprocessor control used for signature detection also has the ability to analyze the current sensing data from the bifilar coiled transformer. and doing so can filter out alias or undesired current transients. This can result in fewer CFCI interruptions in events not effectively attributable to actual earth leakage events.

This condition in general purpose GFCI circuits is generally uncomfortable and has resulted in less enthusiastic reception of sockets

GFCI. How

Smart socket already has a built-in processor, much better resolution in decision making can be obtained, and thus a lower number of false interrupts initiated.

[00070] With reference to figure 9, an additional bifilar coiled transformer 902 is added in the current path, similar to traditional GFCI, and the “felt current differential is amplified by the high gain differential amplifier 901. The signal is presented to the Control and feel module 903 where a 4-bit ladder analog to digital converter (A to D) converts the input analog signal into a digital signal. The data is processed on an interrupt basis on the microprocessor.

If any data the processor does for what it is doing and begins analyzing the data flow from

Petition 870180039271, of 05/11/2018, p. 49/59

42/44 input from the transformer to feel GFCI. At this point, signature analysis algorithms similar to the algorithms used for general current load analysis are applied to the input data. If an event is considered to be a probable GFCI trigger event, the power control relays 940, 950 are energized, thereby in turn disconnecting the AC power source from each of the 907, 908 load sockets.

Since the current detection is in the primary energy path, the two relays must be energized. The ventilation is temporarily registered in the control and feel module 903 and sent to the Central Command Processor via the 909 current transmitter. The ventilation data is also sent to the central command processor for further analysis. The Central Command Processor can determine whether the event data was false or true and act accordingly, or it can wait for user intervention and submit a reset. At any time, the central Command Processor, or a local user can reset the GFCI interrupt condition. This can be accomplished by receiving a command from the Central Command processor via the 909 current receiving modulator or the manual reset button on socket 906 by direct user intervention.

[00071] Power can be momentarily restored to a socket at a time. If the GFCI event still exists, a determination can be made as to which socket is responsible at that time, and the associated LED 910 or 911 can be illuminated and / or flashed.

[00072] In addition, the incorporation of Light Emitting Diodes (LEDs) 910, 911 allows other useful functions to be included in the Zonit Smart Socket. Those

Petition 870180039271, of 05/11/2018, p. 50/59

LEDs 910, 911 can be controlled from the Common Command Processor. The user interface in that place can initiate various functions using LEDs 910, 911 located adjacent to each of sockets 907, 908.

Some of the functions include, but are not limited to:

Leak condition indication for the earth; Indication of excess current condition; Circuit location indication;

Indication of all sockets in a given circuit bypass;
